Basic rules to be followed for Active/Passive conversions are:
1. The object of the active verb becomes the subject of the passive verb.
2. The finite form of the verb is changed (to be+ past participle).
3. The subject of the active sentence becomes the object of the passive sentence (or is dropped).
4. Preposition "by" is used before object.
The given sentence is in active voice. It is simple form of present tense. The structures for active/passive voices are:
Active: Subject + verb (“s“ or “es” with singular noun) + object…
Passive: Object + Is/are/am + verb (IIIrd form) + by + subject…
So, based on the above structures, we can convert the given sentence into passive voice:
